Margin Valuation Adjustment Optimization

The over-the-counter (OTC) derivatives market — with a gross market value of approximately 10 trillion USD — is the largest part of the financial trading market by volume. One of the recent developments in the OTC market is the introduction of initial margin (IM), which is a new collateral requirement for bilateral derivative trades, in addition to the existing variation margin. The cost of funding initial margin is called Margin Valuation Adjustment (MVA), and it forms a new component of the valuation adjustment framework for pricing derivative trades.

MVA requires the calculation of path-wise sensitivities of the portfolio which is computationally intensive. To deal with this computational challenge, we use a machine learning methodology, namely Gaussian process regression, to estimate the future sensitivity profiles. The second challenge in the context of IM is the optimization of MVA as a trading cost, due to its complex and non-linear nature. In this talk, I will present techniques to deal with both the computational and optimization aspect of MVA.
